Wakefieldite-(La) is the lanthanum endpoint of Wakefieldite with the ideal formula LaVO4. As a vanadate in the tetragonal crystal system, the rare-earth mineral is a member of the xenotime group.
Wakefieldite-(La) was first described in 2008 for an occurrence in the Glücksstern mine, Gottlob Hill, Friedrichroda, Thuringia, Germany. [3] Similar to other rare-earth minerals, the type material contained considerable parts of other rare earth elements, namely neodymium, praseodymium, samarium and yttrium. [4]
